K<sub<2</sub<TiF<sub<6</sub<:Mn<sup<4+</sup< phosphors are synthesized via an emulsification method using surfactants as sodium dodecyl sulphonate and oleic acid. The K<sub<2</sub<TiF<sub<6</sub<:Mn<sup<4+</sup< phosphors in ultra-thin and nanosheet crystals are observed via scanning electron microscopy and high-resolution transmission electron microscopy. The surfactants are found to play a key role in inhibition of KTFM crystal growth process and stabilization of Mn<sup<4+</sup< ions doping into the K<sub<2</sub<TiF<sub<6</sub< host. The prepared phosphors exhibited intensive red emission at approximately 632 nm and excellent thermal stability in the range of 300–500 K upon 460 nm light excitation. Moreover, the K<sub<2</sub<TiF<sub<6</sub<:Mn<sup<4+</sup< nanosheets were integrated on InGaN/AlGaN nanowire WLEDs for color quality study. The results show that the nanowire WLEDs with red-emitting phosphor exhibit unprecedentedly high color rendering index ~96.4, and correlated color temperature ~4450 K.

Moreover, the K<sub<2</sub<TiF<sub<6</sub<:Mn<sup<4+</sup< nanosheets were integrated on InGaN/AlGaN nanowire WLEDs for color quality study. The results show that the nanowire WLEDs with red-emitting phosphor exhibit unprecedentedly high color rendering index ~96.4, and correlated color temperature ~4450 K. fluoride nanosheets red emission K<sub<2</sub<TiF<sub<6</sub<:Mn<sup<4+</sup< III-nitride nanowire white light-emitting diodes Mechanical engineering and machinery Thi Tuyet Doan verfasserin aut Barsha Jain verfasserin aut Ravi Teja Velpula verfasserin aut Tung Cao Thanh Pham verfasserin aut Hieu Pham Trung Nguyen verfasserin aut Hoang-Duy Nguyen verfasserin aut In Micromachines MDPI AG, 2010 12(2021), 8, p 965 (DE-627)665016069 (DE-600)2620864-7 2072666X nnns volume:12 year:2021 number:8, p 965 https://doi.org/10.3390/mi12080965 kostenfrei https://doaj.org/article/8365d06d37e5446b86e12c76cbe4be34 kostenfrei https://www.mdpi.com/2072-666X/12/8/965 kostenfrei https://doaj.org/toc/2072-666X Journal toc kostenfrei GBV_USEFLAG_A SYSFLAG_A GBV_DOAJ GBV_ILN_20 GBV_ILN_22 GBV_ILN_23 GBV_ILN_24 GBV_ILN_39 GBV_ILN_40 GBV_ILN_60 GBV_ILN_62 GBV_ILN_63 GBV_ILN_65 GBV_ILN_69 GBV_ILN_70 GBV_ILN_73 GBV_ILN_95 GBV_ILN_105 GBV_ILN_110 GBV_ILN_151 GBV_ILN_161 GBV_ILN_170 GBV_ILN_213 GBV_ILN_230 GBV_ILN_285 GBV_ILN_293 GBV_ILN_370 GBV_ILN_602 GBV_ILN_2014 GBV_ILN_4012 GBV_ILN_4037 GBV_ILN_4112 GBV_ILN_4125 GBV_ILN_4126 GBV_ILN_4249 GBV_ILN_4305 GBV_ILN_4306 GBV_ILN_4307 GBV_ILN_4313 GBV_ILN_4322 GBV_ILN_4323 GBV_ILN_4324 GBV_ILN_4325 GBV_ILN_4335 GBV_ILN_4338 GBV_ILN_4367 GBV_ILN_4700 AR 12 2021 8, p 965

abstract	A two-dimensional nanostructured fluoride red-emitting phosphor with an excellent quantum yield of ~91% is studied for cost-effective and high-color quality nanowire white light-emitting diodes (WLEDs). K<sub<2</sub<TiF<sub<6</sub<:Mn<sup<4+</sup< phosphors are synthesized via an emulsification method using surfactants as sodium dodecyl sulphonate and oleic acid. The K<sub<2</sub<TiF<sub<6</sub<:Mn<sup<4+</sup< phosphors in ultra-thin and nanosheet crystals are observed via scanning electron microscopy and high-resolution transmission electron microscopy. The surfactants are found to play a key role in inhibition of KTFM crystal growth process and stabilization of Mn<sup<4+</sup< ions doping into the K<sub<2</sub<TiF<sub<6</sub< host. The prepared phosphors exhibited intensive red emission at approximately 632 nm and excellent thermal stability in the range of 300–500 K upon 460 nm light excitation. Moreover, the K<sub<2</sub<TiF<sub<6</sub<:Mn<sup<4+</sup< nanosheets were integrated on InGaN/AlGaN nanowire WLEDs for color quality study. The results show that the nanowire WLEDs with red-emitting phosphor exhibit unprecedentedly high color rendering index ~96.4, and correlated color temperature ~4450 K.

K<sub<2</sub<TiF<sub<6</sub<:Mn<sup<4+</sup< phosphors are synthesized via an emulsification method using surfactants as sodium dodecyl sulphonate and oleic acid. The K<sub<2</sub<TiF<sub<6</sub<:Mn<sup<4+</sup< phosphors in ultra-thin and nanosheet crystals are observed via scanning electron microscopy and high-resolution transmission electron microscopy. The surfactants are found to play a key role in inhibition of KTFM crystal growth process and stabilization of Mn<sup<4+</sup< ions doping into the K<sub<2</sub<TiF<sub<6</sub< host. The prepared phosphors exhibited intensive red emission at approximately 632 nm and excellent thermal stability in the range of 300–500 K upon 460 nm light excitation. Moreover, the K<sub<2</sub<TiF<sub<6</sub<:Mn<sup<4+</sup< nanosheets were integrated on InGaN/AlGaN nanowire WLEDs for color quality study. The results show that the nanowire WLEDs with red-emitting phosphor exhibit unprecedentedly high color rendering index ~96.4, and correlated color temperature ~4450 K.</subfield></datafield><datafield
